| Cat.No.: | Kit-2051 |
| Product Overview: | This Fluorimetric NADP Assay Kit provides a rapid and sensitive method for the measurement of NADP. The proprietary probe used in this kit reacts only to NADP to generate a product that has fluorescence at Ex/Em=420/480 nm, it has almost no response to NADPH. |
| Size: | 200 assays in 96-well plates |
| Description: | Nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+) are two important cofactors found in cells. NADH is the reduced form of NAD+, the oxidized form of NADH. NAD forms NADP with the addition of a phosphate group to the 2" position of the adenyl nucleotide through an ester linkage. NADP is used in anabolic biological reactions, such as fatty acid and nucleic acid synthesis, which requires NADPH as a reducing agent. In chloroplasts, NADP is an oxidizing agent important in the preliminary reactions of photosynthesis. The NADPH produced by photosynthesis is used as reducing power for the biosynthetic reactions in the Calvin cycle of photosynthesis. The traditional NAD/NADH and NADP/NADPH assays are done by monitoring the changes in NADH or NADPH absorption at 340 nm. This method suffers low sensitivity and high interference since the assay is done in the UV range that requires expensive quartz microplate. |
| Applications: | The assay can be performed in a convenient 96-well or 384-well microtiter-plate format. Its signal can be easily read by a fluorescence microplate reader at Ex/Em = 420/480 nm.This kit has been used for screening enzyme activities that use NADP/NADPH as a cofactor. It has also been used for the sensitive detection of NADP in cell-based assays. |
| Storage: | Keep Component A in freezer (-20°C) and avoid exposure to light; Component C at -20°C; Component B &G at 4°C. |
